Abstract (en)

[origin: EP2431189A2] A recording medium includes an ink-receiving layer on a substrate, in which the ink-receiving layer contains a hydrated alumina, an alkylsulfonic acid having 1 to 4 carbon atoms, and at least one salt of a sulfur compound represented by general formula (1) or (2): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 1 -SO 2 M 1 €ƒ€ƒ€ƒ€ƒ€ƒgeneral formula (1) €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 2 -SO 2 -SM 2 €ƒ€ƒ€ƒ€ƒ€ƒgeneral formula (2) wherein R 1 and R 2 each represent an alkyl group, an aryl group, or a heterocyclic group; and M 1 and M 2 each represent an alkali metal, ammonium, or an alkanolamine. The proportion of the alkylsulfonic acid having 1 to 4 carbon atoms is in the range of 1.0% by mass to 2.0% by mass with respect to the hydrated alumina. The proportion of the salt of the sulfur compound is in the range of 0.2% by mass to 4.0% by mass with respect to the hydrated alumina.
